STANGHION.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application-filed June 8, 1910. Serial No. 565,756.

To all whom it may concern:

Be it known that I, ARTHUR F. A. TIoY- MAN, citizen of the United States, residing at Mayville, in the count-y of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Stanchions, of which the following is a specification.

This invention relates to stanchions and has for its object the provisions of a comparatively simple and thoroughly eflicient device of this character, the construction of which is such as effectually to prevent a cow from leaving its stall, whileat the same time permitting the animal to turn its head in any direction.

A further object is to provide a stanchion including a supporting frame having a yoke pivotally mounted therein and provided with a movable section, the lower end of said yoke being free to move laterally with respect to the supporting frame.

A further object is to provide improved means for locking the movable section of the yoke in closed position, and means for releasing the locking means.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efliciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a stanchion constructed in accordance with my invention; Fig. 2 is a rear elevation of the upper portion of the stanchion, showing the movable section thereof in open position; Fig. 3 is a rear elevation of the lower portion of the stanchion; Fig. 4 is a detail perspective View of one of the supporting brackets detached; Fig. 5 is a similar view of the segmental plate or bar detached; Fig. 6 is a perspective view of the U-shaped locking member detached.

Corresponding and like parts are referredto in the followin description and indicated in all the views 0% the drawings by the same reference characters.

The improved stanchion forming the subject matter of the present invention comprises a supporting frame including spaced uprights 5 having brackets 6 secured to the inner faces thereof and rovided with laterally extending flanges i for attachment to transverse connecting bars 8 and 9. The flanges of the lower set of brackets are preferably disposed in alinement with the lower ends of the adjacent standards 5 so as to form a smooth bearing surface for the supporting frame, while the upper set of brackets are preferably spaced from the upper ends of the standards 5.

Pivotally mounted within the supporting frame is a yoke 10 having a movable section 11, the lower end of which is pivoted to the body of the yoke, as indicated at 12, while the upper end thereof is reduced to form a terminal lip 13. One end of the yoke 10 is provided with a vertically disposed pin 14 which extends through a correspondingly shaped opening in the upper connecting bar 8, while the lower end th reof is provided with a foot piece 15, the bottom of which is pivotally connected with a sliding plate 16. The plate 16 is slidably mounted in suitable guides or keepers 17 secured to the bottom of the connecting bar 9, the intermediate portion of the plate being bowed upwardly so as to prevent the pivot pin 18 from coming in contact with said connecting bar. Thus it will be seen that the lower end of the yoke is pivotally connected with the plate 16, while the latter is free to slide within the keepers 17 so as to permit the lower end of the yoke to be adjusted laterally with respect to the supporting frame and thus prevent said yoke from cutting or otherwise lacerating the neck of the cow when the animal lies down in its stall.

Secured to the upper end of the pin 14 is a collar 19 to which is secured one end of a coil spring 20, the opposite end of said spring being fastened in any suitable manner to one of the bars of the supporting frame 5. The tension of the spring 20 is such as to return the yoke to normal position when the latter is tilted 011 its pivotal axis, as by reason of the cow turning its head.

The flanges 7 of the brackets are provided with a plurality of spaced openings for the reception of pins or bolts 21, such a construction permitting the connecting bars 8 and 9 to be adjusted in a horizontal plane to accommodate cows of different sizes.

is provided with an upwardly and inwardly extending lug 26 which rides over the segmental rack 22 and forms in effect a guide for the yoke when the latter is swung in either direction on its pivotal axis.

Secured to the intermediate portion of the segmental rack 22, is one end of a chain or other flexible element 27, the opposite end of which passes over a guide pulley or roller 28 for. attachment to a transverse rod 29 slidably mounted in suitable keepers 30 secured to the standards on one side of the supporting frame.

port 32, while the intermediate portion thereof is pivotally connected with the rod 29, so that by tilting the lever the rod 29 will be moved longitudinally and through the mediumof the chain 27 elevate the plate and release the locking member 25 from engagement with the terminal lip 13 of the movable section 11 of the-yoke, when it is desired to position said'yoke on the neck of a c'ow. In order to close the movable section of the yoke, there is provided a chain 33, one end of which is secured to the free end of the movable section 11, the opposite end of said chain being extended over a guide roller or pulley to a second slidingrod 34 n to which is connected a lever 35 similar in construction to the lever 31. Thus ,it will be seen that by tilting the lever 31, the locking member 25 will be elevated to disengage the movable yoke section 11 so as to allow the yoke to embrace the neck of an animal e The and bytilting the lever 35, the section 11 may be moved to closed position, the locking member25 dropping by gravity into en.- gagement with the terminal lip 13 and preventing tilting movement of said movable section. V V

' stanchions may be made in different sizes and shapes and any number of such stanchions connected in any suitable manner, without departing from the spirit of the invention.

NVhile I have shown the stanchion formed of wood, it will, of course, be'understood that the same may be constructed of piping, tubular metal, angle iron or the like.

Having thus described the invention, what is claimed as newis:

1. -A stanchion including a supporting One end of an operat-- ing lever 31 is pivotally mounted on a supframe, a yoke pivotally mounted in the frame and provided with a movable section, a bar, a locking member adapted to engage the movable yoke section for holding the latter in closed posit-ion and provided with a guide lip bearing against the bar, and means operatively connected with the locking member for releasing the latter.

2. A stanchion comprising a supportin 0' frame including spaced uprights connected by transverse bars, one of which is provided with an opening, a plate slidably mounted on the lower connecting bar, a yoke having H a vertical pin journalcd in the opening of the upper bar and having its lower end pivotally connected with the plate, saidyoke being provided, with a movable section, means for locking the movable section in closed, position, and means for releasingthe locking means.
